<!-- <p style="text-indent:2em;"> I am a senior researcher at Tencent, where I work on computer vision and information retrieval. 
      I finished the M.S.-Ph.D. study and obtained my Ph.D. degree from Xiamen University in 2022, advised by <a href="https://mac.xmu.edu.cn/rrji_en/" target="_blank">Prof. Rongrong Ji</a>.
	  Earlier, I received the B.S. degree from Fuzhou University in 2016.
  </p>
  <p style="text-indent:2em;">My recent research interests are to develop efficient vision models, image/text retrieval, as well as vision/language pretraining.</p> -->

  Welcome! I am currently in my final year as a Graduate student majoring in Artificial Intelligence at <a href="https://mima.sdu.edu.cn">MIMA</a> Lab, Shandong University, advised by Associate Professor <a href="https://faculty.sdu.edu.cn/luoxin/zh_CN/index.htm">Xin Luo</a>, co-advised by Professor <a href="https://faculty.sdu.edu.cn/xuxinshun/zh_CN/index.htm">Xin-Shun Xu</a>. Before that, I received my Bachelor's degree in School of Information Science and Engineering, University of Jinan, Jinan, Shandong, China, in 2022, supervised by Associate Professor <a href ="http://2021.yzadm.ujn.edu.cn/Page/Dsxx/ssds_data/ssds_id/a8ba7dfc-7b89-18f8-af5c-5c4705349712/status/1.html">Peng Wu</a>, <a href ="http://2021.yzadm.ujn.edu.cn/Page/Dsxx/ssds_data/ssds_id/a8ba7dfc-7b89-18f8-af5c-5c4705349712/status/1.html">Jie Su</a>, and Professor <a href ="https://ujnview.github.io/">Xiuyang Zhao</a>. I deeply appreciate the dedicated guidance and support.
  <br>
  <br>
  My current research topics are Machine Learning and Multimedia Retrieval. I mainly focus on <b>retrieval</b>, especially online hashing and image/cross-modal retrieval. Besides, I am also open and willing to explore other tasks, e.g., <b>vision-language model</b>, LLMs, test-time adapatation, incremental learning, prompt learning, and federated learning. 
  <br>
  <br>
  <b>If you are interested in my topics, please do not hesitate to reach out.</b>
